WATER-CLOSET Bowl..-

SPECIFICATION forming part of Letters PatentfNo. 499,194, dated June 13, 1893.

Application filed January 2s, 1893. seria No. 460,015. er@ modal IO tents when the bowl is being used will be quickly and thoroughly removed, and of such construction that an objectionable sucking or gurgling noise will not be produced when the bowl empties, and to prevent the contents I5 of the traps after the main flushing has taken place from being siphoned out as is the case with many old styles of bowls.

The invention consists in the bowl to be described herein, and set forth in the claim.

In the drawings Figures 1 and 2 are side and plan views, respectively, of the improved bowl, and Figs. 3 and 4 are vertical sections on the broken lines a', fr, and y, y, respectively of Fig. 2.

In the drawings Ais the closet bowl.

B is the point of connection of an inlet water pipe, not shown, connected to suitable means for admitting water for flushing the bowl, and therefrom extend three branching Passage a leads directly to the rim d, of the bowl, which is hollow, and is perforated on its lower overhanging ledge e, as shown in Fig. 3, such flushing rims being old. The passage b eX- A3 5 tends to the bottom of the main trap or basin part of the bowl, and has a contracted outlet f which points up the main discharge pas- `sage g, see Figs. 1 and 3. The passage c extends under the passage g, andup to the top 4o of the bowl, communicating with the outlet g, through the opening h. v,

i is a plug or valve, by removal of which, admission may be gained to some of the passages if desired.

v j is an air passage extending from the main outlet passage gto the upper part of passage c, and communicating therewith through an opening la.

Zis the main trap of the bowl, and m is a 5o second trap or basin formed by a weir or dam n in which the water may just close the passage g from below, so that the slightest agitation of the water will unseal the trap sufficiently to allow of vthe air contained in the main discharge passage g to be forced below the dam fn, while a steady flow of water will cause said trap to be sealed. vIt will be seen that by this means I am enabled to produce a Vacuum with the least possible delay which feature taken in connection with other elements of my device I consider of importance.

When the apparatus is inits normal condition, with its traps lled as shown, and water is admitted at B, by any suitable means, such for example as shown in my Patent No.

436,451, September 16, 1890, the stream divides into three streams. One stream, forming the suction jet, passes through passage c, and into passage g at h in the direction of the arrow, Fig. 3. Thus the rush of water through passage g agitates the water in the trap msufficiently t0 allow the air contained in said passage to be forced below the dam 'n and a further steady iow of the water through the passage g will cause said trap m to be sealed and a vacuum to be created back of the trap Z, causing the contents contained within the bowl to be siphoned out through said passage g,t.o the discharge pipe. Simultaneous with the above described operation, a stream or jet of water issues at f, in the direction of the arrow, Fig. 3,which tends to directly and forcibly eject the contents of the bowl through passage g. Also simultaneously with the described operations a third stream passes from the hollow rim, to the bowl through openings e, thus washing the whole inner surface of the bowl. The water rushing through passage c, closes the opening lo, of the air passage j, so that said opening does not prevent the perfect operation of the siphon in emptying the bowl. But as soon as theiniiow of water at B, ceases or largely diminishes, the upper bend of passage c becomes emptied of water, thus uncovering the opening k, and air will rush in through said opening. This will check the siphoning action; the lower bend of passage c will remain full of water, thus forming a trap for sewer gas. After the main flushing of the bowl is accomplished, as described, sufficient water flows down to ll the bowl, as indicated in Fig. 3. This leaves the bowl in condition' for a subsequent use.

Evidently the suction and force jets may IOO be used in combination with the secondary trap, sometimes, without the passage leading to hollow of the bowl, and it is not essential that the several passages described should have just the form and arrangement shown in the drawings.

Awater closet bowl A, having a main trap or basin Z, a second basin fm formed by the weir n, and two water passages c, b, one leading from the water inlet B to the main discharge siphon passage g, and communicating with said passage g through an opening adapted to form a downward jet through the longer FRED ADEE.
